VENTlLATOR.

SPECIFICATION forming part of Letters Patent No. 787,377, dated April 18, 1905.

Application filed April 21, 1904. Serial No 204.243.

To u u'lmm/ may con/(c171 Be it known that l, SAMUEL l). l'lANNlCY, a citizen of the United States of America. and

a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators, of which the following is a specilication.

This invention relates to the type of ventilators which consist of a tubular member adapted to be secured along a wall or win dow-sash and serving as a hand-rail, sash-lift, &c., besides controlling the admission of air through such wall.

The main object of my invention is to provide improved construction for ventilators of this class, reducing the labor of applying the same, increasing the strength, improving the appearance. and facilitating the work of cleaning dust and other accumulations from the interior of the same. I accomplish this object by the device shown in the accompanying drawings. in which Figure l is a top view of a combined sashlift and ventilator constructed according to my invention. Fig. 2 is an elevation of the face of the same which is disposed toward the window. Fig. 2:3 is a horizontal section on the line 3 3 of Fig. 2. Fig. & is a transverse section on the line T T of Fig. 1.

ln the emistruction shown the member 5 consists of a straight tube having a pair of brackets ('3 extending transversely therefrom. The brackets l' are disposed in parallel relation to each other and are provided at one end with ornamental bands T, which encircle the tube 5 and are braced orotherwise rigidly secured thereto. The shanks of the brackets 15 are hollow and form branch tubes communicating with the interior of the member The outer ends of the brackets 6 forln annular shoulders 8, adapted to bear on the opposed face of the sash t) or other wall to which the ventilator is secured. The shanks of the brackets 6 are internally threaded and are adapted to receive the threaded end of the hollow nipple ll). The nipples 10 are preferably uniform in trz'insverse diameter and are provided at their outer ends with transverse annular flanges 11, adapted to bear on the outer face of the sash. The tube 5 is provided with a plurality of air-holes or perforations lQon the face which isdisposed toward the sash and with the apertures 13, communicating with the tubes 10. Each end of the tube is closed by a plug. The plug l-t on one end is rigidly secured to the tube and has an annular groove extending around its inner end adjacent to the walls of the tube The plug 16 is movably mounted in the end of the tube having the pocket 15), said plug being rotatable therein and rem 'able therefrom. A curved plate 17, litting the inner surface of the tube 5, has one end rigidly secured to the plug l0, while its opposite free end seated in the groove 15 in the end of the plug 14:. The plate 17 extends through the entire length of the tube 5 between the plugs and is of sullicient breadth to entirely close the perforations l2 and the apertures 13 when it is rotated to a certain position. The plug 16 is provided with a transverse projecting stud l8, and the tube 5 is pressed outwardly at 19 to form a pocket for receiving the stud 18. The pocket at 19 is disposed transversely of the tube 5 and is of sullicient length to allow the plate 17 to be turned from a position entirely closing the apertures in the tube 5 to an open position. The pocket at 19 has a branch 20 connecting the same with the end of the tube 5 and adapted to permit the plug lo and the plate 17 to be withdrawn from the tube.

The operation of the device shown is as follows: in applying the device to a windowsash or wall it is merely necessary to bore two holes of uniform diameter through the sash in suitable position to register with the brackets 6 and of suitable diameter to snugly litthe nipple ll). The nipples 10 are then passed through the holes and secured into the brackets 6 until such brackets are tightly clamped to the sash. \Vhen the plug l6 is turned to its limiting position in one direction, the apertures lb and all of the perforations I) will be open, so as to permit a free flow of air from the outside of the wall or window through the brackets 6 and finally through the perforations 12, or vice versa. A movement of the plug M5 to its other limiting position entirely closes all of the apertures, since the plate 17 ported in the groove 15, thus effectually preventing said plate from swinging away from the walls of the tube 5.

To clean dust and other accumulations from the interior of the tube, the stud 18 is turned to a position opposite the branch pocket 20, when the plug and plate 17 may be withdrawn endwise out of the tube 5. The rotation of the plate 17 within the tube 5 serves to scrape and gather the dust from the interior of the tube 5, so that when the plate 17 is withdrawn from the tube all of such accumulations come with it and may be readily cleaned off. It will be seen that the comparatively narrow plate 17 is much more easily cleaned than would be the case if the same were a perforated tube closed at one end by the plug 16.

The brackets 6, with their bands 7 encircling the pipe 5, form a strong and rigid structure adapted to easily bear all of the strain to which the device is likely to be subjected when used as a sash-lift, hand-rail for Stairways, or any other device for which its shape is adapted.

It will be seen that some of the details of the construction shown may be altered with out departing from the spirit of my invention.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a ventilator, the combination of a tubular member, a supporting-bracket encircling said member and havinga hollow shank communicating with the interior of said member, extending transversely of said member and adapted to abut endwise against a wall or the like; a nipple of uniform external diameter adapted to pass through the wall and enter theadjacent end of the shank, and having threaded engagement therewith; a flange on the end of said nippleadapted to abut against the other side of the wall; and means within said member for controlling the passage of air therethrough, substantially as described.

2. In a ventilator, the combination of a tubular member having air-holes through its walls; a branch tube rigidly secured to said tubular member and having a longitudinal passage extending through the same and communicating with the interior of said member; a plug fitting one end of said member and movable therein; a valve-plate secured to said plug and extending along the interior of said member and adapted to control the flow of air through said branch tube and air-holes; and a part secured to the tube at the free end of said plate and having a seat bearing against plug and extending along the interior of said member and adapted to control the flow of air through said branch tube and air-holes; a second plug in the opposite end of said tube and having at its inner end a seat adapted to receive the free end of said plate, substantially as described.

4. In a ventilator, the combination of a tubular member having air-holes through its walls; a branch tube rigidly secured to said tubular member and having therein a longitudinal passage communicating with the interior of said member; a plug fitting one end of said member and rotatabl y mounted therein; a valve-plate secured to said plug and extending along the interior of said member and adapted to controlthe flow of air through said branch tube and air-holes; a second plug in the opposite end of said tube and having in its inner end an annular seat adapted to receive the free end of said plate, substantially as described.

5. In a ventilator, the combination of a tubular member having air-holes through its walls; a branch tube rigidly secured to said tubular member and having therein a longitudinal passage communicating with the interior of said member; a plug fitting one end of said member and rotatably mounted therein; a valve-plate secured to said plug and extending along the interior of said member and adapted to control the flow of air through said branch tube and air-holes; a stud projecting transversely from said plug, the walls of said tube being pressed outwardly to form a seat for said stud, and said seat being of suitable form to limit the rotation of the plug and prevent the same from being withdrawn from said member except when the plug is rotated to a certain position, substantially as described.
